Definitions
- the invention relates to a method for producing a semitransparent motor vehicle design element.
- the invention also relates to a method for producing a display or signal element.
- the invention relates to a motor vehicle design element produced according to the method according to the invention, a display or signal element, and a vehicle headlight comprising one according to the invention
- Motor vehicle design element design element and a motor vehicle comprising a motor vehicle design element according to the invention.
- Motor vehicle design elements that should be colored in particular, or should have matt or glossy surfaces, are typically designed as plastic components, the final appearance of the surfaces usually being determined by painting with appropriate paints. In this way, colored, glossy or matt vehicle headlight design elements can be produced.
- a disadvantage of conventionally produced motor vehicle design elements is that paints usually have a considerable layer thickness that cannot be less than a minimum in order to have covering properties - the layer thicknesses can typically be more than 100 micrometers or more.
- the application of paints is time-consuming, on the other hand, the surface structure of the plastic component is covered by the required layer thickness of a paint and is not completely reproduced.
- the color impressions and color effects that can be achieved with lacquers are also limited due to their composition and the type of application, with typically only the body's own colors being able to be applied to the substrates for reasons of cost.
- the body's own colors are colors in which the color impression is created through the absorption of individual color components of the light falling on the body. Optimization of the properties of coatings has so far been achieved by changing the coating process and the composition of the paints to be applied.
- One object of the invention is therefore to create a method for producing a motor vehicle design element which has an improved visual appearance.
- the present invention enables a metallic color coating of at least partially translucent plastic substrates, with the production of different cold and warm design lights being made possible.
- the term "translucent” relates to light in a wavelength range that is visible to the human eye.
- the expression “semitransparent layer” means that this layer for light which penetrates from the rear side in the direction of the front side through this layer passes through this layer with a transmittance between, for example, 10% and 90%.
- the expressions “rear side” and “front side” denote each other opposite sides of the substrate or of the motor vehicle design element resulting therefrom.
- the rear side can be a first side and the front side a second side.
- the directional information "front” and “rear” are therefore freely selectable from the point of view of the substrate are generally interchanged - only in connection with further features mentioned below are certain properties and layer structures assigned to these pages.
- the motor vehicle design element is used in connection with an active light source that is set up for at least partial illumination of the motor vehicle design element, with the term “back” denotes that side of the motor vehicle design element that is assigned to this light source and can be irradiated by the light source, so that light emitted by the light source propagates through the motor vehicle design element from the rear to the front in the substrate and on the front out of the Substrate or the motor vehicle design element emerges.
- the first layer is designed in such a way that the first layer reflects light that occurs on the first layer from the front side in the direction of the rear side of the substrate. D In this way a kind of Venetian mirror can be created.
- the first layer has a degree of reflection of at least 50% and / or a degree of transmission of at most 50% in a direction of light propagation from the front side to the rear side of the substrate.
- the front side can be provided with anisotropic reflective properties, so that light that strikes the front side in the direction of the rear side is reflected to a higher degree than light that propagates in the opposite direction.
- the term “transmittance” (regularly referred to in the specialist literature with the Greek symbol “x”) is understood to mean the inverse ratio of the light incident on a medium (ie the light incident on the light entry surface of the medium) to the transmitted radiation power. The light falls at a right angle on the light entry surface of the medium.
- the first layer has a degree of reflection of at most 80% and / or a degree of transmission of at least 20% in a direction of light propagation from the rear side to the front side of the substrate.
- the method further comprises the following step,
- steps B and C application of a light-absorbing cover layer to the front or back of the substrate, the opaque cover layer containing at least one transparent opening for displaying at least one graphic symbol, steps B and C being carried out in such a way that from the back towards the front of the Substrate through the at least one opening of the opaque cover layer for projection of the at least one graphic symbol represented by the at least one opening impinges on the first metallic semitransparent layer and at least partially penetrates the first metallic semitransparent layer to the outside.
- the sequence of steps B and C) can in principle be freely selected.
- the graphic symbol can also simply be a square, a circle, a stripe, etc., e.g. to display fuel caps.
- the opaque cover layer is applied by means of a PVD process, the at least one transparent opening being exposed by lasers.
- the layer thickness for achieving this opacity is very small compared to other materials.
- the expression “opaque” is understood to mean that the degree of transmission is less than or equal to 0.001, ie a maximum of one per thousand or 0.1%.
- the degree of transmission of “opaque” objects within the meaning of the present invention can be 0.01%, 0.001% or even be exactly 0%.
- the opaque cover layer can also be designed to be light-absorbing.
- the cover layer can also be light-absorbing.
- the opaque cover layer is designed in the form of a film. This can be an adhesive film or a deep-drawn film which is sprayed onto the substrate.
- the opaque cover layer is arranged on the rear side of the substrate.
- the opaque cover layer is arranged on the front side of the substrate.
- the first layer is arranged directly on the light-absorbing cover layer.
- the opaque cover layer is arranged on the rear side of the substrate.
- the opaque cover layer is opaque.
- the first layer is arranged on the rear side of the substrate.
- the first layer is arranged on the front side of the substrate.
- the first layer has a layer thickness between 2 nm and 300 nm.
- the pressure of the vacuum chamber is less than IO 2 mBar, preferably less than ICD mBar. It can preferably be provided that the method also includes the following step:
- the second layer is largely free of body colors, with a body color being a color that can be recognized by at least partial absorption of spectra of visible light, the extent of the absorption of the color components red, green and blue being unequal, wherein the second layer is designed in such a way that the color composition of the light reflected by the motor vehicle design element is manipulated by interference of at least one spectral component of the light.
- the expression "largely free” means that the color effect is mainly caused by the interference and not by the absorption of spectral components in the material, i.e. the degree of absorption for visible light within the frequency spectrum (400 nm to 800 nm wavelength) of visible light, e.g. less than 30 % fluctuates.
- the second layer is applied by sputtering, with titanium being provided by a sputtering target, for example, which reacts with oxygen as the reactive gas introduced into the sputtering process and thus forms a titanium dioxide layer on the first layer, with default the coating rate and / or the duration of the coating process, the layer thickness of the second layer is specified.
- a combination of titanium (knocked out of the sputtering target) and oxygen (as reactive gas) can produce a large number of (interference) colors (blue, gold, violet, green, yellow), the actual color depending on the thickness of the coating .
- Exemplary "recipes" for an entire coating structure can be as follows:
- a suitable sputtering target that enables the application of a metallic layer
- the metal of the metallic layer can be selected from the following list: ⁇ Titanium, chromium, silicon, aluminum, stainless steel, copper, zirconium ⁇ .
- a base layer e.g. HMDSO using PECVD
- the so-called first layer follows, consisting of one of the metals mentioned or mixtures thereof with the omission of a reactive gas. This is followed by a second shift using a reactive gas, such as oxygen.
- a metal ceramic is created by the chemical reaction of the metal with the reactive gas.
- metal-ceramics usually have distinctly different properties than pure metals, such as high hardness, high chemical resistance and significantly different optical properties (e.g. transparency) - which enable color to be generated via interference. Due to the small layer thickness, the properties of these metal ceramics are not necessarily to be regarded as the same as the properties of the same material as bulk material (titanium dioxide, for example, is no longer transparent in higher thicknesses, but a white powder - white pigment).
- the sputtering target preferably remains changed, ie the same starting metal can be used as in the first layer.
- the protective layer already mentioned can optionally be applied.
- the first layer and the second layer are selected in such a way that at least partial light permeability is ensured for light that propagates from the rear side to the front side through the substrate and the layers.
- the second layer consists of the same starting material as the first layer.
- the second coloring layer is applied with the addition of a reactive gas during the sputtering process.
- a reactive gas in addition to the inert gas (e.g. argon) required for sputtering, a further gas (or a gas mixture) is provided in the sputtering chamber, which reacts with the material knocked out of the target and thus changes the deposited layer (
- titanium detached from a sputtering target can react with oxygen to form titanium dioxide and thus form a titanium dioxide layer on the substrate or the first layer.
- Such layers can have a significantly changed property spectrum due to the chemical change based on the reaction with the reaction gas (e.g. metal can suddenly take on ceramic or glass-like properties).
- Any gas that can be used as a reactive gas is can react with the metal. Usually, however, oxygen, nitrogen or carbon-containing gases (CO or acetylene or methane) or mixtures thereof are used.
- a semitransparent effect mirror layer is arranged after the first layer for partially reflecting light rays back to the first layer or optionally a second layer, this effect mirror layer is arranged from the first layer at a distance of at least 1mm, with light-permeable material being arranged between the effect mirror layer and the first layer so that light rays passing through the first layer from the rear towards the front side of the substrate can be reflected between the first layer and the effect mirror layer and can be radiated to the outside through the effect mirror layer.
- graphic symbols can be impressively displayed.
- the “mask” - that is, the opening that determines the image - is introduced directly into the lower opaque layer (which can be designed as a completely reflective (non-semitransparent) metal layer, for example).
- the mask can be designed as an opening in an opaque layer which is attached behind the completely continuous first semitransparent metal layer LI.
- the layer sequence in this aspect of the present invention is as follows: opaque (optionally absorbing) layer LD / substrate 1 / semitransparent metal layer LI (LI and 1 can also be interchanged under certain circumstances) / optional coloring layer L2 (this can be applied directly to LI) / translucent material V / semi-transparent effect mirror layer L3 / optional coating CL. So that a metal layer is semitransparent, layer thicknesses in the range of a few nm (penetration depth) can be provided. A large number of metals can be used as the material, such as Al, Au, Ag, Cu, Cr, etc.
- EP 0256635 A2 describes the opening in the diaphragm
- EP 0256635 is designed as a "pinhole" which is as small as possible, which is used to align a measuring instrument.
- the subject of the present invention is the rendering of a graphic symbol, and nothing with the alignment of measuring instruments.
- the effect mirror layer has a degree of reflection of at least 50% with respect to light which impinges from the front side in the direction of the rear side of the substrate.
- the effect mirror layer has a transmittance of at least 50% with respect to light which enters the effect mirror layer from the front side in the direction of the rear side of the substrate.
- the first layer and the effect mirror layer are inclined to one another at least in sections in order to change the angle of the light rays reflected between these layers. This results in a visual change, in particular a distortion, of the mirror images.
- the PVD process according to step B) is designed as a sputtering process.
- step C) takes place with the omission of a reactive gas during the sputtering process.
- the temperature in steps B) and C) is below 100.degree. C., preferably below 70.degree. C., particularly preferably below 60.degree. This is how it is The method according to the invention can in principle also be applied to substrates which have a lower temperature resistance.
- step D) takes place by sputtering with the addition of a reactive gas, in particular oxygen.
- the second layer is obtained by providing titanium by a sputtering target which reacts with oxygen as a reactive gas introduced into the sputtering process and thus forms a titanium dioxide layer on the first layer, with the coating rate and / or The thickness of the second layer is specified for the duration of the coating process.
- the PVD process according to step B) is designed as a thermal evaporation process.
- PVD processes are e.g. electron beam evaporation, laser beam evaporation, arc evaporation (arcen).
- the first layer comprises aluminum.
- This first layer can be applied, for example, by a non-reactive sputtering process.
- Aluminum has a reflectance that can be precisely defined as a function of the layer thickness and is therefore particularly suitable for use as the first layer.
- Non-reactive sputtering process which is suitable for applying the first layer, should be mentioned as an example: Argon gas is let into the vacuum chamber (up to the desired pressure range, e.g. lxlCHmbar), the target (cathode) is energized - the anode is usually supplied by the Chamber wall or the devices shown, through the voltage the argon ionizes (to Ar +) and is accelerated towards the cathode (negatively charged), through the (mechanical) impact of the argon ions, the impulse is transmitted to the atoms of the target - is sufficient If energy is present, some of the target atoms dissolve and fly into space.
- Argon gas is let into the vacuum chamber (up to the desired pressure range, e.g. lxlCHmbar)
- the target (cathode) is energized - the anode is usually supplied by the Chamber wall or the devices shown, through the voltage the argon ionizes (to Ar +) and is accelerated towards the ca
- the distance of the atomized atoms is so high that they can reach the substrate and condense there.
- the basic material for the applied layers is present as a target in the sputtering process (usually metals, but it can also be ceramics).
- the first and optionally a second layer are formed in such a way that light incident on the layers from the front side in the direction of the rear side of the substrate is reflected in such a way that the at least one opening provided in the light-absorbing cover layer if there is no backlighting is not visible to the human eye.
- the expression backlighting is understood to mean an arrangement in which light originating from an active light source provided for this purpose is emitted through the rear side in the direction of the front side through the opening to the front.
- a protective layer is applied by means of plasma polymerization over the first layer, or optionally over a second layer covering the first layer, this protective layer being in particular a layer consisting of polyhexamethyldisiloxane.
- the protective layer is designed in such a way that the color composition of the light reflected by the motor vehicle design element is manipulated by interference of at least one spectral component of the light.

- This method is suitable for producing an opaque motor vehicle design element 3 (see FIGS. 4, 5 and 6) and comprises the following steps: A drawing on a dimensionally stable, at least partially translucent substrate 1 which is heat-resistant to a temperature of at least 60 ° C., the substrate 1 having a front side and a rear side,

- argon gas 4 is admitted into the vacuum chamber 2 (up to the desired pressure range, for example 1 ⁇ 1 cmbar), a target 5 being placed under tension with respect to, for example, the chamber wall 6.
- argon ionizes (to Ar +) and is accelerated towards the cathode 5 (negatively charged).
- the impulse is transferred to the atoms of the target - if there is sufficient energy, some of the target atoms will dissolve and fly into space; if the pressure in chamber 2 is sufficiently low, the flight distance of the atomized atoms is so high that they can reach the substrate 1 and condense there.
- the base material for the applied layers is present as target 5 in the sputtering process (usually metals, but this can also be ceramics). Two different possibilities are sketched as target 5 in FIG. 1 - for example, the target could consist of aluminum or also of titanium. Aluminum is very well suited for producing the already mentioned first layer LI. When generating the first layer LI, the presence of a reactive gas is dispensed with.
- the aluminum condenses in its pure form on the target.
- an alternative scenario is also shown, namely one in which, for example, a titanium target is used and the knocked-out titanium material or the titanium atoms react with a reactive gas 7 - in this case oxygen - to form titanium dioxide and condense on the substrate 1.
- a second layer L2 (see FIGS. 5 and 6) can be produced.
- the first layer LI is first applied in a non-reactive sputtering process, and then, after the introduction of a reactive gas, the second layer L2 is applied over the first layer LI.
- the first layer LI and - if present - the second layer are selected in terms of their composition and layer thickness such that they are at least partially transparent to light that penetrates through the substrate 1 from the rear side 1b of the substrate 1 to the front side 1b .

- FIG. 5 shows the aforementioned light beams LSI and LS2 which are superimposed on one another, the color of the light reflected by the design element 3 being able to be influenced by the superimposition.

- the provision of the protective layer CL changes the reflection behavior of the second layer L2 and thus of the light rays LS2, insofar as the protective layer CL has a relative permittivity that differs from that of air.
- the protective layer CL can thus be designed in such a way that the color composition of the light reflected by the motor vehicle design element 3 is manipulated by destructive interference of at least one spectral component of the light.
- the effect mirror layer can in principle be constructed in the same way as the first layer LI. It can therefore consist of the same material.

- the second layer L2 can be largely free of body colors, a body color being a color that is recognizable by at least partial absorption of spectra of visible light, the extent of the absorption of the color components red, green and blue being unequal, the second layer L2 is designed in such a way that the color composition of the light reflected by the motor vehicle design element 3 is manipulated by interference of at least one spectral component of the light.
